分块矩阵的偏等距
Partial Isometry of the Partitioned Matrix
摘要
Abstract
Under the condition of disjointness of the column space and row space,and according to the definition of the partial isometry,the partial isometry of two kinds of the partitioned matrix is studied.Several necessary and sufficient conditions for partial isometry of its submatrices are obtained when the partitioned matrix is partial isometry matrix.关键词
